ALCOHOL-LAMP.

Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed October 9, 1912. Serial No. 724,889.

To all whom it may concern Be it known that I, Louis WoJinKow, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Alcohol-Lamps, of which the following is a full, clear, and exact description.

The object of this invention is to provide a simple lamp, in which substantially all of the alcohol, or other burning fluid, is ab sorbed by the wick in the first instance, eX- cepting that a slight overflow or excess may be utilized as a sort of primer or initial burner, for heating the burner sufliciently to start vaporization of the fluid absorbed in the wick within the burner, and to ignite such vapor.

The invention comprises a holder having a reservoir and a surrounding saucer-like flange, and a removable burner having a wick tube of substantially the same dimensions as the reservoir filled with any suitable wicking and adapted to be fitted in the reservoir, and in the act of being so fitted therein to absorb substantially all of the burning fluid save a small quantity overflowed thereby into the saucer-like flange, which, when ignited will furnish heat enough to start vaporization of the burning fluid within the burner and ignite it and thus establish the flame at the burner, which flame continues until the burning fluid is exhausted, unless sooner extinguished.

The invention is susceptible, of a variety of embodiments, some of which are herein shown and explained in illustration of the principle of the invention.

In the accompanying drawings illustrating the invention in the several figures of which like parts are similarly designated, Figure 1 is a top plan view; Fig. 2 is a side elevation; Fig. 3 is a top plan view of the holder, and Fig. 4 is a longitudinal section illustrating one form of the lamp. Fig. 5 is an elevation of the burner detached. Fig. 6 is a longitudinal section showing the burner of Figs. 1 to 5 provided with a screen, as in Fig. 7. Fig. 7 is a half section and elevation illustrating other modifications.

The holder comprises a tubular reservoir 1 having at its top a laterally extending saucer-like flange 2, preferably provided with an annular trough 3, and a handle 4:. Excepting that the reservoir is adapted to hold a given quantity of burning fluid and the flange is adapted to receive any overflow of such fluid, these parts may be of any approved construction and material.

The burner comprises a tube 5 adapted to be filled with any suitable wicking or absorbent material 6, and of a size to fit snugly within the reservoir and to absorb the fluid therein while being so fitted, in such way that any surplus fluid will overflow into the flange and collect in the trough so as to furnish fluid to be ignited to serve as an initial burner in heating the burner proper sufliciently to vaporize the fluid within and to ignite such vapor as it issues from the burner. A foraminous diaphragm 7 is secured Within the upper end of the burner so as to limit the upward extension of the wick within such burner. Above this diaphragm is the burner tip 8, of any suitable construction, and consisting preferably of a flared wall 9 provided with a perforated crown 10, the vapor collecting within the chamber 11 formed by the diaphragm 7, wall 9 and crown 10 and issuing in jets through the perforations in the crown. The wall 9 overhangs the trough 3. The diaphragm may be held within a knurled or otherwise formed head 12.

As shown in Figs. 4 and 5, the lower end of the burner may be left entirely open and scalloped or otherwise formed; or as shown in Figs. 6 and 7 it may be closed by a foraminous cap 13, frictionally or otherwise engaging the burner tube. But it is preferred to make the burner in such way that the wick may be renewed whenever neces sary, by any inexpert person.

Excepting for size and details of construction and shape, and the screwthreading presently described, the lamp shown in Fig. 7 is substantially like that already described. In order to prevent the operator from shoving the burner into the holder or reservoir so suddenly as to preclude the absorption of the burning fluid by the wick,

and to splash out and waste such fluid, the upper portion of the holder-or; reservoir 1 is provided with a screwthread 14:, and the upper portion of the burner tube 5 is pro vided with a con'iplementary screwthre'ad 15, so that the burner has to be turned into the holder in order to properly insert it therein. By this means the operator is prevented from thrusting the burner into the holder suddenly or violently. Moreover the screwthreads prevent accidental separation of the burner from the holder, and facilitate the disconnectionof the two should they stick by the gumming of the fluid in burning.

In operation, the burner is removed from the holder, and a quantity of burning fluid is then placed in the reservoir, preferably enough to fill it. Then the burner, supplied with the necessary absorbent wick, is slowly placed in the holder so as to allow the wick to absorb the burning fluid. Some of the fluid will collect or overflow into the trough 3, and then when the burner is fully inserted within the holder a light is applied to the burning fluid in the trough, which isignited, and by impinging on the wall 9.heats the burner sufliciently to vaporize the fluid, and the vapor issuing in jets; through the crown is ignited by the flame from the burning fluid in the trough, and the lamp burns until its supply of burning fluid is exhausted or it is extinguished.

The lamp is useful for manypurposes, but is especially useful where articles are to be cooked more or less, as eggs, for example, since by regulating the quantity of burning fluid, the lamp may be prepared toiburn for any number of minutes. In this. way, for example, eggs may be boiled soft, medium or hard without further attention from the cook.

Theselamps may be made of anydesired size, and of any desired fluid .eapacity,.but

I. have found that a lamp two inches high,

measured from the burner tip to the. bottom of the holder, and with a :flange of two inches diameter, will burn long enough to boileggs hard. It is to be noticed that the burner fits the reservoir substantially tight, but not so tight as to prevent its easy. removal- In inserting the burnerin the reservoir, it may be dropped therein and allowed to settle by gravity, sofas to avoid splashing,

and 1n the case oflamps constructed in.ac-. cordance with Figs. 1 to 6, thefit of the burner within the reservoir should be sufficiently tight to ,preventthe accidental displacement of the burner. Inthe form gOf.

lamp shown in Fig. 7, the screwthreading,

as already stated, not only absolutely pre-.

vents theuser from. forcing the-burner home in the reservoirsuddenly, butadmitsof a loose fit between the burner and the reservoir, and also insures the retention of the burner in the reservoir against accidental displacement.

" The lamp of Fig. 7 may be provided with any suitable handle, for'example, one similar to that shown in Figs'l to 6.

Although the invention is entitled an al cohol lamp, and is so claimed, it is to be un derstood that the invention is not limited to the use of alcohol as the burning fluid. Any

suitable vaporizable fluid may be used.

, WVhat I claim is 1. An alcohol lamp, comprising a-reser- ,voir having a saucer-like flange surrounding its upper edge, and a removable burner, comprising a burnerv tube of substantially the same dimensions asthe reservoir and provided with av wick and adapted to be fitted within the reservoir and its wick therebyabsorbing substantially all the fluid withinthe reservoir, and a burner tip on said tube sep-' arated from the wick by a vapor chamber, the flange serving to receive fluid to be ignited. beneath the burner tip to start-vaporization in saidburner.

' 2. An alcohol lamp, consisting of a holder whichcomprises a reservoir for-the fluid, and a surroundingflange adapted to receive a quantity of burning .fluid to be ignited for starting vaporization, and a removable burner comprising a wick-receiving tube of substantially the same dimensions as the reservoir and adapted to fit the reservoir, a foraminous diaphragm in the wick tube to limit the inward-projection of the wick,and a tip made up of a side .walloverhanging the flange, a perforated crown, and a vaporizing chamber interposed between the foraminous diaphragm and the crown.
